2 Claims. 1

This invention relates to improvements in folding machines and more especiall to improvements in a machine of the type shown in United States Letters Patent No. 2,336,507 issued to Albert F. Shields, on December 14, 1943.

In the conventional folding machine, largesized box blanks of, for instance, corrugated board are placed on the bed of the machine and as they are fed into the machine they are folded so that portions of the blanks are folded from both ends of the blank inwardly to where the opposed ends of the blank will meet each other and the folded blanks are then fed into a taping mechanism which applies an adhesive strip along the meeting folded edges in order to create a rectangular tube after the blank has been removed from the machine. In the present machines, various adjustments can be made in the component parts of the machine to permit various sizes of blanks as well as various sizes of the portions to be folded on said blanks being fed through the machine. However, in th present structure due to the variations in the location of the meeting points of the folded portions of the blank, it is not possible in many cases to properly aline this meeting point with the tape applying means.

It is therefore an object of this invention to provide a tape applying means in combination with the folding machine which may be adjusted transversely of the machine so as to aline the tape within the tape applying means properly with the meeting point of the opposed edges of a blank after it has been folded.

It is another object of this invention to provide heating means for applying heat to the surface of the tape, after having been previously treated with a dried adhesive material, so that when moisture is applied to the surface of the tape, the tape will be more adhesive than it would be if no heat had been applied thereto.

It is another object of this invention to provide a conveyor which may be adjusted transversely of the machine so that the conveyor will be in alinement with the meeting points of the folded portion of the blanks after they have been fed through the taping mechanism.

Some of the objects having been stated others will appear as the description proceeds when taken in connection with the accompanying drawings in which Figure 1 is a plan view showing the discharge end of the folding machine and showing the feed end of a conveyor associated therewith as well as the improvements made in the machine;

Referring more specifically to the drawings the numeral 22 broadly designates the framework of the machine. This framework 22 i cal-led a bed 22 in said patent. The frame 22 comprises side frame members Ill and II which are connected at their lower ends by a transverse angle bar I 2 and intermediate their upper and lower ends by transverse channel bars I3 and I4 and by an upper transverse angle bar I5 all of which are secured to or are integral with the vertical side frame members I0 and I I.

. which, for purposes of clarity, is shown in dotted lines inasmuch as it is a conventional part of H the folding machine.

Mounted for horizontal sliding movement on the upper flanges of the channel bars I3 and I4 are spaced plates Ill and longitudinally of the machine and haye' fixedly mounted thereon a plurality of studs which.

extend upwardly from. the same and have rotatably mounted thereon grooved rollers 280 which are the same as those shown in- Figure 13 of said patent. The plates II? and I I-B'eachhave a boss which is threadably penetrated by threaded-shafts 26 and 21 respectively which are rotatably mounted in the vertical side frame members I0 and I I, respectively.-

Welded to the discharge ends of the spaced plates Ill and II 8 are L-shaped blocks I 6 and II, respectively. These blocks It and I1 have, pivotally mounted therein, parallel blocks I Q. The blocks IB- and I! have, rotatably mounted on the proximate ends thereof, rollers 39, and the parallel blocks I9 have, rotatably mounted, on the proximate ends thereof, rollers 42. rollers 39 and 42 are disposedabove each other so that each edge ofthe blanks B will pass between them as they are discharged from the tape mechanism. The upperrollers 42 are urged downwardly towards the rollers 39 'by tension springs 49, the-upper ends of which are m'ounted onspring perches 54, secured on the parallel blocks I9. The lower ends of the springs 4-9 are mounted in spring perches 4I-, secured to the L-shaped blocks [Band 11.

The shafts 26 and 21 have secured on their outer ends sprocket wheels 28 and 29, respectively, which are engaged-my sprocket chains -3 I and 32, respectively, which extend to a conventional driving mechanism; not shown. This driving mechanism is usually an electric motor'which is energized to rotate theshafts 2'6 and 21 the desired amount for a particular set-up. The plates Ill and H8 havedownwardlyprojecting and transversely disposedribs 33 which are adapted to slidably engage a groove 34 in the transverse channel member I4 (Figures 1 and 20) By referring to. Figure 3 of said patent there may be observed ashaft 3.6 whichismountedin the bed 22. of the machine, andthis shaft 3fi-has secured thereto a pair of sprocket wheels 31 and 38 on which, are mounted sprocket chains 23 and 24, respectively. There is shown in Figure 2 of my; invention a pair of sprocket chains 23 and 24. which are identical to the sprocket chains shown in the said patent, and I mount between these chains 23 and 24 a sprocket chain 35. The sprocket chains 23,. and 24 are mounted on sprocket wheels 36, 37,,and' 38, respectively, which are fixedly mounted on a shaft 40; It will be noted in Figures 2'and 9 that the sprocket wheels 36, 31 and 33 are integral with each other. 7 e

The shaft 40' isdisposed transversely of the machine at its discharge end and is rotatably H8 which extend" Meshing with the bevel gear isa bevel gear 41 which is fixedly mounted on a. shaft which is rotatably mounted in the gear box 46 and extends to the left in Figure 3 and has mounted on the end thereof a pinion 5| which meshes with a pinion 52 fixedly The secured on the end of a shaft 53 which extends downwardly in Figure 1, or to the left in Figure 3 and is connected to the folding means which is not pertinent to this invention and is thereforenot shown.

As heretofore stated the sprocket wheel 43: is disposed outside of the vertical side frame member I0 and is secured on the shaft 40. The sprocket wheel 43 has'mounted thereon a sprocket chain 51 which extends downwardly in Figure 3 and is mounted on a sprocket wheel 58 which, as may be observed in-Figure 2, is fixedly mounted on the end ofa shaft 59 which extends from an electric motor fiflhaving'electric wires BI and 62 leading therefrom to a suitable source of electrical energy. Thus themotor 65 impartsrotation to the shaft 59 and thesprocket wheel 58 which, in turn, imparts rotation to the shaft 40.

ihe sprocket wheel 44 adjacent the sprocket wheel 43 on thesha'ft' lthas mounted thereon a sprocket chain which, as may be observed in Figure 3, is also mounted on sprocket wheels 66, 6'6; 68 and 892 The'sprocket wheel 56 is fixedly mounted-on-th'e end of a'shaft II which is rotatably mounted in the vertical sideframe-member is and extends therethrough and is rotatably mounted in the side frame member I! at its other end (Figure 2).

The sprocket Wheeliil-is disposed-directly above and in spaced relation to the sprocket wheel 66 and is fixedly mounted on the endof a shaft I2 which is also rotatably mounted in vertical side frame member ld-and extends therethrough and is rotatably mounted in the vertical side frame member I! at its other end; The sprocket wheel 88 serves as anidl'er andisrotatably mounted on a stud 8i! which is-secured'in a bracket til-secured to thetop surface of the vertical sideframe member Ill (Figures 1, 2 and3);

The sprocket wheel 69-is rotatably mounted" on a shaft 85 and-has drum portion 86 integral therewith. The interior surface of the drum portion 86 is engaged by a clutch mechanism, not shown, having clutch extending therefrom (Figures 1 and 2) which,-whenthe clutch is in engagement with the drum portion 85;are engaged at their proximate ends by-the collar sleeve 90 which is keyed to the-shaft 85 and-has horizontal sliding movement-thereon. This sleeve 98 is grooved as at 9I andsaid groove is-engagedby a fork member '92 which extends downwardly in Figure l and 'is fixedly secured on the end of a shipper shaft 931 The shipper shaft 93 is mounted for horizontal sliding movement in a bearing block 94 (Figure 1) which extends downwardly from the shaft 93 and is secured by any suitable means such as screws 95 to -a dovetailedguidebar NIB which is disposed transversely of the machine and is-secured at each end thereof to the vertical sideframe members I and II by any suitable means such as screws IOI.

The shaft 93 extends towards the center of the machine and penetrates a block I03 and is slidably mounted at its free end in a boss I04 which is integral with the tape mechanism frame broadly designated at I05, to be presently described. The block I03 is secured on the shaft 93 by a set screw I01, and the block I03 extends downwardly.

and engages one end of a horizontally disposed lever bar I I0 (Figures 8, 9, and 16) and is moun ed on the end of the lever bar Ill! by a shoulder screw III (Figure 8). The lever bar IIO extends towards the discharge end of the machine and is oscillatably mounted at I I2 on an upwardly projecting portion I I3 which projects upwardly from the tape mechanism frame I05. The lever I I0 has a handle portion II integral therewith.

All parts heretofore described with the exception of the dovetailed bar I00, are conventional parts of the folding machine. The top part of the tape applying mechanism is conventional, but the lower portion has various novel improvements made in the same and it is more especially desired to bring out the use of a slidable tape applying mechanism to be mounted on the dovetailed bar The shaft 85 (Figure 2) on which the clutch actuating collar 90 is slidably mounted, is rotatably mounted in a bearing block II9 which extends downwardly from the shaft 85 and is secured by any suitable means such as screws I20 (Figures 1 and 21) to the top surface of the dovetailed bar I08 and at the left-hand end thereof is secured to the vertical side frame member I0, by any suitable means such as screws I2 I, as observed in Figure 21. The shaft 85 extends through the bearing block I I9 and has fixedly mounted thereon a sleeve I22 b any suitable means such as a set screw I23 (Figure The sleeve I22 has grooves I24 extending longitudinally thereof which are engaged by projecting ribs I28 disposed longitudinally of the shaft 85 and at opposite sides of the shaft 85. The sleeve I22 extends to the right as observed in Figures 2 and 10 and has mounted therein for horizontal sliding movement, one end of a shaft I28 having keys I30 integral therewith which engage the slots I24 in the opposed internal surfaces of the sleeve I22.

The sleeve I22 will thereby permit lateral adjustment of the shaft I28 in the sleeve I22 for purposes to be later described. The shaft I28 extends out of the sleeve I22 and has fixedly mounted thereon a sprocket wheel I35, having a sprocket chain I36 mounted thereon and extending upwardly from the same (Figures 2, 3 and 9).

The upper end of the endless sprocket chain I38 is mounted on the sprocket wheel I31 (Figures 2 and 3) which is fixedly mounted on a shaft I40 which is rotatably mounted in a box-like housing I42 (Figure 1) having bearing blocks I43 therein. The box-like member I42 has a heavy partition I46 therein which extends rearwardly in the box-like member I42 towards the discharge end of the machine.

The shaft I40 extends through the partition I48 of the box-like member I42 and has mounted on the end thereof a roller I48 which is secured on the end of the shaft I40 by a nut I49 (Figure 4) Disposed below the roller I48 and on the same vertical frame is the roller I3I which is rotatably mounted on a stub shaft I52 and confined thereon by a nut I53. (Figure 4). The stub shaft I321 of the idler roller I5I isfixedly mounted in the par-' tition I46.

A shaft I55 fixedly mounted in the box-like housing I42 "extends through the partition I46 and has rotatably mounted on the end thereof a roller I58 which-has wound therearound suitable tape I80 which has been chemically treated with a dry adhesive. The tape I00 passes between the driven roller I48 and the idler roller I5I' and extends downwardly to a pin I8I which is fixedly secured in the vertically disposed partition I48. The tape then extends upwardly to and is mounted on a roller I62 which is fixedly mounted on a shaft I63 (Figures 1 and 4) and the tape I60 then passes out of the box-like member I42 through an opening I65.

The shaft I83 on which the roller I32 is fixedly mounted'extends through the wall I43 and exand I13 are rotatably mounted on a stub shaft I14, said stub shaft being fixedly secured in the box-like member I42. The sprocket wheel I13 is engaged by the sprocket chain I38 to thus have rotation imparted to the same and in turn impart rotation to the sprocket wheel I12 and thus to the sprocket wheel I10 mounted on the shaft I83. The box-like member I42 is secured by any suitable means such as screws I15 (Figures 4 and 9) to the top surface of the tape mechanism frame I05.

By referring to Figures 9 and 12 it may be observed that the frame member I05 has an outwardly projecting portion I integral therewith on the vertical side surface of which a plate member IBI is secured by any suitable means such as screws I82. This plate member I8I has integral therewith, and disposed towards the discharge end of the machine, a boss I84 which is threadably penetrated by a horizontally disposed threaded shaft I88 which extends to the left as observed in Figure 18 and has an enlarged portion, not shown, rotatably mounted in a portion I81 of a sliding member I88. This portion I81 also confines the end of the shaft I83 therein by means, not shown, so that the shaft I88 may be moved to the right or to the left as observed in Figure 18 and thus cause the slide I38 to be moved to the right or to the left.

. The plate I8I' is slotted as at I98 (Figures 9 and 18) and the slide member I88 has integral therewith a smaller slide member I82 which has horizontal sliding movement in the slot I90. This sliding member I92 has a stub shaft I93 projecting therefrom on which is rotatably mounted a roller I94.

The roller I94 penetrates a slot I95 in a plate broadly designated at I98. The plate I06 also has an opening I91 therethrough, through which the shaft I28 passes. The shaft I28 has fixedly mounted thereon a cam wheel I99 which is disposed adjacent the plate I'QB (Figures 9 and 18) and this cam wheel I 39 has a raised lobe 20 I which is adapted to engage a pin 202 fixedly mounted in the vertical face of the plate I93. It is thus seen that by rotation of the shaft I28 the lobe 20I of the cam wheel I89 will intermittently engage the pin 202, projecting from the plate I96,

and will: thus urge theplate upwardlyagainst the pullof a tensionspring 258,: and the plate willbe- The guided by the roller I94 in the slot I95: threaded shaft I86is usedfor adjusting .the roller I94 to theright or to the'left 'asobservedin'Figure, 18'to thereby move the (pin 202- relative to the shaft-I 28'. This will of. course decreaseor in-.- crease the angular movement-of the platelet.-

by the cam wheel I39.

The lower end of the plate I95 (Figure-18) has. fixedly secured thereto, byany suitable means; such as'screws 295, a rack 295 which is adapted rotatably mounted on oneend: thereof a roller- 2| I. havingv a resilient rubber covering; 2 l 2.

The roller H l is hollow and has internal ratchet.

teeth 2I3 thereinlwhich are adapted to be engaged by a torsion spring dog member 214 which has oneof its ends, fixedly mounted on the end of. the shaft 2fllby any suitable means such as screws 2H5 (Figure 17). Thepurposeof the ratch-- et mechanism, which. is a form of over-riding clutch, is.to permit the rack 205 to move downwardly while imparting rotation, in a counterclockwise direction, to the shaft 261, in-Figure 17, without turning the roller 2i I. On the other hand, upon'eachupward stroke of the rack-"235, in Figure 17, the shaft 2!}? will transmit astep inrotation to theroller 2i I ma clockwise direc* tion in' Figures. land 17.,

Referring again to Figure 18, it may be observed thatthe rack 2u5=is held in engagement with the pinion 206 by a peripherally grooved sleeve 229 whichfispenetrated by abolt 221 which also penetratesthe outwardly. projecting portion; 250. of. the frame I05 andithus secures the grooved sleeve 221] thereto.

The shaft IZBextends throughthe frame member I05,- asheretofore. described,.and has fixedly. mounted thereon a camwheel 225 having a radial.- ly disposed shoulder22t on its :outersurface forming one wall. offia cavity 221;. This-.camwheel '225 (Figures 9 and 19.) is engaged-by. a-block member 228 which is integraLwith alever. bar. 229.. which is pivoted as at23ii to. the vertically disposed tape mechanism frame member E85. Theright-hand endiof; the leveribar 2253::(Eigure 19).- hasesecured.

thereto=as at 23f. ad-downwardly; projecting ten: sion spring232 whichis secured'atitslower end as .at 233. to-the verticallyd-isposed tape mechanism frame member I05.

It is' thus seen that the: horizontally disposed lever bar. 229 is. urged downwardly at its righthandend in Figure 19 .to thusxcause theblocki223 to be held-.inconstant engagement with.the pe-. ripheral surface of the cam member 225.?. It is obvious that asthe block 228 falls int'o the cavity 221 of the cam 225 the right-hand end of the lever 229' (Figure 19) will be urged downwardly and the left-handend of the samewill be raised upwardly.

Thelever bar 229 has pivotally secured-to the left hand endthereof, as at 235 a vertically. ad-. justable connecting rod 236 the lower endof which is pivotally connected as at 23$- (Figure '9) to -a horizontally disposed lever bar 238 which is 'pivotally mounted as. at zsil 'on-thevertically. disposed frame member I 95 and-has secured-on'ithe end thereof a cutter blade' 2 ii',.byany suitable meanssuch as screws 242a When'the'blade- 241 is moved downwardly from the position shown in Figure9, it will'engagea mating blade-243 (Figures 4 and 9) I which is integral with a cast mem-.

her 246 having a slot 241 therethrough in which a roller 248 is disposed, said roller being rotatably mounted in each side of the cast member 246 as observed in Figure 9.

The cast member 246 is forked at its other end and is oscillatably mounted on a shaft 250 which. is fixedly mounted on an outwardly projecting portion 25I of the cast frame member I05. The-cast frame member I has a downwardly projecting dovetailed'portion 253 which has an outwardly projecting portion 254 (Figure 4) which has-engaging the upper surface thereof an adjustment screw 255. This adjustment screw 255 is-to adjust the relative position of the roller 248 to the roller 2 having the rubber covering 252 thereon to thus cause rotation of the roller 2 to move the paper tape I58 towards the cutting blades 24 and 243.

The tape I50 passes over the roller I62 as heretofore stated and extends downwardly adjacent the right-hand vertical surface of the box-like portion I62 as observed. in Figure 4 and successively engages pins 256, 251 and 258 which are fixedlymounted in the vertically disposed bracket 26llwhich extends downwardly into a water reservoir ZEI and is welded to the bottom of the same, The Water reservoir 26! is secured by any suitable meanssuch as screws 262, to an outwardly projecting horizontally disposed portion 2835 of the frame member I135.

Also fixedlymounted at one end in the bracket 266i is a shaft 261 (Figures 4, 8 and 9) which has rotatably mounted thereon a. roller 2'16 and the other end of the shaft 26? is fixedly mounted in another vertically disposed bracket 2' (Figures 8 and 9) which is also welded to the bottom of the reservoir 26L The reservoir ZBI has a suitable liquidsuch as water 26 1 therein in whichlthe roller 2h) is partially submerged and as the roller 2 I0is caused to rotate through contact with the tape I60, some of the liquid will-adhere to the outer peripheral surface of the roller 270. and thus will be transmitted to the lower surface of the tape I60 as it passes over the roller 2').

So that the cam wheel 225 may be adjusted around the-shaft I28, there is disposed between the cam wheel 225 and the vertically disposed tape mechanism frame member 855 a plate 275 (Figure 9) which is fixedly mounted on the shaft I223. The opposite face of the cam member 225 is integral with-a drum portion Z'lt having a hand wheel 21.? integral therewith (Figure 9). The cam wheel 225, the drum member 2.16 and the hand wheel. 21']. being integral are allrotatably mounted on the shaft I28 and by turning the hand wheel 2H the position of the shoulder 226 of the cam wheel 225 may be adjusted relative to the shaft I28 However, before the hand wheel 27'! may be turned a hand wheel. 286] must: be turned inasmuch as the hub 28I of the hand wheel 280 engages the right-hand surface of the hand wheel 27'! as observed in Figure 9. This hand wheel 280 is threadably mounted on the end of the shaft I28. Thus, by turning the hand wheel 280 relative to the shaft I28 the hub portion 28! of the hand wheel. 23!) will be moved away from the hand wheel 27.! and thus allow the cam wheel 225 to be adjusted relative to the shaft I28.-

Fixedly mounted on the intakeedge-of the tape mechanism frame-member- IE5 is a-down-a wardly projecting dovetailed member 285 (Figures 4, 12, 18 and 19), which is similar to the downwardly projecting portion 253, and is disposed in spaced relation thereto so that the tape mechanism frame member H may be guided by the dovetailed bar Hlfl. This plate 285 is secured to the lower edge of the tape mechanism frame I05 by any suitable means such as screws 286 and has integral therewith a boss 23'! which is threadably penetrated by a shaft 288 (Figure 12).

By referring to Figure 1 it may be observed that the shaft 288 extends from the tape mechanism frame member I35 to the left and is rotatably mounted in a bearing portion 293 of the vertically disposed side frame member It. The shaft 288 has fixedly mounted thereon collars 29! and 292 which are disposed to each side of the bearing portion 290 to thus prevent endwise movement of the shaft 288. The shaft 283 has mounted on the outer end thereof a hand wheel 293 having a handle 294 integral therewith which may be grasped by an operator for turning the shaft 288. By turning the shaft 253 the relative position of the tape mechanism frame member I55 may be adjusted relative to the vertically disposed side frame members If! and l I. That vertical surface of the tape mechanism frame member 155 which is nearest the intake end of the machine has mounted thereon, by any suitable means such as screws 299 threaded into holes 298, a bracket 3130 (Figures 4 and 8) which extends towards the feed end of the machine and has an upwardly projecting portion 30l integral therewith which is braced between its upper end and the tape mechanism frame H35 by a diagonally disposed brace member 332 which is secured to the bracket 350, by any suitable means such as welding.

Extending from the vertically disposed portion 30! of the bracket 30!) are horizontally disposed spaced strap iron bars 353 which are welded at their other ends to a vertically disposed strap iron member 304 (Figure 4). The vertically disposed strap iron member 334 has mounted thereon, by any suitable means such as welding, a plurality of incandescent bulb receptacles each designated by reference character 3%. These bulb receptacles 306 each have threadably mounted therein, in a conventional manner, incandescent bulbs indicated at 301. These bulbs 38! are conventional heat bulbs and are disposed in spaced relation to that portion of the paper tape Hill which extends from the roller I23 (Figure 4) downwardly to where it engages the first horizontally disposed pin 25S heretofore described to thus apply heat to that surface of the tape I55 which has been treated with the dry adhesive to thereby cause the adhesive to be more adhesive after contact with water than it would be if the heat were not applied.

Electrical energy is transmitted to the incandescent light bulbs 301 by branch wires 353 and 309 which extend from lead wires 3! l and 3M (Figure 4). The lead wire 3 extends downwardly to one side of a male plug 315 and the wire 3l2 extends downwardly to one side of a switch 314 and the other side of the switch connected to a lead wire 3 I 5 which leads to the other side of the male plug 316, thus by inserting the male plug 3|6 into a suitable source of electrical energy, not shown, by closing the switch 3E4 the electrical energy will be transmitted to the incandescent bulbs 30'! to thus cause heat from 5 10 the same to be applied in the manner heretofore described.

Fixedly mounted on that surface of the dovetailed plate 285 which is towards the feed end of the machine is an angle clip 325 which is secured thereto by any suitable means such as screws 32l fitting into threaded holes 3l9 (Figures 4, 8 and 12). Mounted against the lower surface of the horizontal leg of the angle clip 320 is a bar 322, by any suitable means such as screws 323. By referring to Figure 8 it may be observed that the bar 322 has grooves 324 in each side thereof in which portions 325 and 325 of a bar 321 are mounted for horizontal sliding movement. This bar 321 is similar to the bar I I3 of said patent and is provided for the same purpose. This bar 321 has a slot 333 extending longitudinally thereof and is joined together at its end nearest the feed end of the machine by a portion 33!.

The portion 323 of the bar 321 has fixedly mountedthereon a rack 332 (Figures 1 and 8) which extends longitudinally thereof and near its end which is nearest the feed end of the machine it'engages a pinion 333 (Figure 1) which is fixedly secured on a transverse shaft 334 mounted in a bearing block 336 which is integral with and projects upwardly from the longitudinally disposed bar 322. The shaft 334' has collars 34!) mounted thereon at each side of the bearing block 336 to thus prevent endwise movement of the shaft 334. The longitudinally disposed bar 322 is secured, at its end nearest the feed end of the machine, to' the lower surface of the transversely dis-posed angle bar [5, by any suitable means such as a screw 34!, which penetrates an adjustment slot 342 in the horizontally disposed angle bar I5.

It may be observed in Figure 1 that the horizontally disposed shaft 334 extends to the left and slidablypenetrates one end of a sleeve 345 having key ways346 therein which are adapted to engage keys 341 of the shaft 334 (Figures 1, 13 and 14). The other end of the sleeve 345 is fixedly engaged by one end of the shaft 348 having keys 350 integral therewith which are also adapted to engage the key Ways 3% in the sleeve 345. The sleeve 345is secured on the end of the shaft 348, by anysuitable means such as a set screw 35!.

The shaft 348 then extends to the left as observed in Figure 1v and is rotatably mounted in a bearingblock 352 integral with the vertically disposed side frame member II and the end of the shaft 348 has fixedly mounted thereon a hand wheel 354. By turning the hand wheel 354 to thus transmit rotation to the pinion 333 on the other end of the 'shaft 334, the pinion, being in engagement with the rack 332 will adjust the bar 321 towards or away from the discharge end as may be desired to accommodate various sized blanks.

By referring to Figure 8 in may be observed that there is disposed between the rollers 200 a blank broadly designated at B having inturned flaps 353 and 354 the proximate edeges of which are to be joined together by the tape 1 53. These blanks B are fed into the machine in the manner shown in said Patent 2,336,507. As the blanks B are fed into the machine, they are engaged by angle bar 355 having a cutaway portion 356 therein (Figures 8 and 15). Although the cutaway portion 356 is shown in one position in the angle bar 355 in Figure 8, the angle bars 355 may easily be removed and replaced by angle acre-e47 bars having the cutaway' portion 355= ina dinerent position so that the bar 322 and associated parts may be adjusted to the right onto the left as observed in Figure 8, as desired. Th'e angle bars 355 have integral therewithand disposed near each end thereof angle clipsv 358;each of which have a slot 359 which, is adapted; to be mounted on a, transverse shaft 350". extending through the link chains 23", 35fandy24; The-slot 359 engages a restricted portion 331 onthe shaft 360. and this restricted portion36l is also enaged by a transversely disposed locking clip. 362 having a, slot 363 therein which engages therestricted portion: 35I of the shaft 3.6 and is mounted for horizontal slidinlg movemention a rivet 364' which is secured in the angle.clip-358. It is thus seen that the angle bars..355l may be easily removed from the. sprocket chains25j 35 and 24 by merely moving the locking c1ip 32to the right as observed in Figure 15 andby raising the angle bars 355 upwardly to move, them from engagement with the shaftv 360.

It may be observed in Figures 4, 8' and .15 that thesprocket chains 23; 3518116]; 24 are supported between the sprocket wheels disposed. at' each end thereof on aplate 3.7.fl whiclrismounted on the transversely disposed channel members. i3 and I4 by any suitable. means-such as welding,

By referring to. Figures 1, 1A and 22130.7; inclusive, there maybe observed an endless .beltconveyor broadly designated at, 3.'i:5;' This conveyor comprises endless conveyor belts. 3J6 3T1 which are disposed one abovetheother-andextend longitudinally from the discharge end of;the machine. The belt 316 is" mounted atonexend on a pulley 318 and) at its'discharge'end' on a roller 319. While, ontheother; hand; the-endless belt 311 on the lower portion of-=the conveyor is mounted on pulley, 382 androller-"383' at the feeding end and discharge'end, respectively: The pulleys 318 and 382 are mounted on-the shafts l land 12, respectively, and are. se'curedt-hereto by any suitable means such as set screws 385 'and 386,- respectively (Figure 6'). Disposedateach end of the pulley 318'and supported by'the-shaft 72 are bearing blocks SSH-in which'th'eshaft 12 has rotational movement. Disposedat each-end of the pulley 382 and supported on the sha-ftTl are bearing blocks 39l in which the shaft Ti has rotational movement. Thus the sha-ftsTi-and? 12 transmit rotation to the pulleys 3l8-and 382 to thus move the conveyor belts 31'6 -and 311; The bearing blocks 3% are secured, by any suitable means such as screws 394, to-a longitudinally extending channel bar 395 which hassecured to the discharge end thereof, by any suitable means such as screws 3%, a pair of bearing blocks 391. which are disposed each side of the-roller379 and have rotatably mounted therein: a-shafti398 on which the roller 3 l9'is fixed-lymounted; The channel bar 395 has integral therewith and extending upwardly from each side thereof the vertical legs of the inverted U-shapedmembers 433 and 45!- the upper-ends Qf-W-hich are'penetrated by shafts 432 and 403 which. are -rotatablysmounted in the U-members 400'Iand' 40L. The extreme ends'of the shafts 402 and 403," at the discharge end of the machine; have-fixedly mounted thereon hand wheels 404 and-485 respectively. The-shafts 402 and 403 are connected 'by universal joints 4% and 451, respectively, to shafts 4'08'w'and3i409, respectively. These shafts in 'turnare connected bya universal joint 4-! I and 412; respectively; to the shaft I85'and toe-shaft 4|5. The shaf-t 4'l5 is threadably connected as'shown in Figure 19 't'o the pivot point 230 in a conventional manner for adjusting the pivot point 230cm a horizontal plane; TheU-shaped members 436 and 4%! are also penetrated by a hooked member 4!! at each of their upper ends thereof and these hooks 4H penetrate a horizontally disposed channel bar 418 of- U-shaped frame members broadly designated at-42fl and 421. The hooked members 4i! are secured in the horizontally disposed channel members 418', by any suitable means such as nuts 423. The hooked members 4!! penetrate transverse slots 425m the transverse channel bars 498 to thus allowadjustment of the conveyor 3]5. it is thus seen that the channel bar 395 is suspended from the channel bar 4 i 8 by the U -shaped members 400 and4ill. The U-shaped members 400' and 40! have rotatably mounted therebetween rollers 426 and 427, respectively, over which the conveyor belt 313 is adapted to pass.

The inverted U-shaped members 429 and 42l have extending downwardly from each end of the channel bars 438 vertically disposed channel bars 428 which are welded to the horizontally disposed channel bars M8 and are welded at their lower ends tohorizontally disposed angle bars 429 which are adapted to rest on the floor F.

The-bearing blocks 39I which are mounted on the shaft H, extendtowards the discharge end of the conveyor 3'l5and are secured, by any suitable means such as screws 432' to rearwardly ex tending channel bar 433. The discharge end of the channel bar 433has fixedly secured thereto, by any suitable'means such as screws 435, bearing blocks 435 Which have rotatably mounted therein, a shaft43'i; The roller 383 is fixedly mounted' on the shaft 431 between the bearing blocks 436. The channel bar 433 is mounted near its discharge end and intermediate its end on transverse channel bars 442"whi'ch" are welded at each end to the vertically disposed channelbars 42'8 of the invertedU-shaped frame members 421) and '42l.

It maybe observed in Figures 5' and '7'that there is di'sposedbetween the downturned flanges oi the channel bar 433 a plurality of rollers 449 which have shafts 441 extending therethrough and-these shafts 44'l' extend outwardly from each end of the rollers 443" and are rotatably mounted in the-zd'ownturned flanges of'the channel bar 433. Theirollersfi' l i'fl project through" the web portion of" the" channel bar 433 through opening 443. Thustheconveyor' belt 31'! passes along the uppersurfacet of thechannelbar 433-and alsopasses over and-engagesthe-rollers 443i Disposed in superposed'relatiorrto:the*conveyor belt 37-? as it passes over the channel'bar- 4331s the lower portion of the conveyor belt-313: These conveyor beltsa3-il and 31(rpa-ssoner: the rollers hand there isdisposed. above the,- lcwer' reach of the be1t-316 transverserollers 444 whichare rotatably mounted as at-.-.445 in..the..lower ends of arms 446 which extend -upwardly,,towards,the feed end of the machineandareapivotallyl mountedias at 44'! to, the downturned. flanges of the channel bar 335. There is one of these. arms 446 disposed on each side of, the channel bar 395for each of the rollers 444. These arms 446" are spanned by bars 450 (Figure 7) on the center of which is mounted the lower'end' of "a; compression spring 45| which extends-- upwardly and engages the lower surface of the webportion of the longitudinally extending channel bar 395 to thus urge the rollers 444 downwardly'against the upper surface of the lower reachof the conveyor belt 315 so that as the folded and taped blanks pass 1 be tween the proximate surfaces of the conveyor belts 316 and 311, the pressure of the rollers 444 against the belt 318 will serve to hold the tape I68 against the joint formed by the proximate ends of the flaps 353 and 354 of the blank B While it is passing between the belts 316 and 3" so that by the time it has reached the end of the conveyor 315 there will be no tendency for the tape to come off the blank B.

The lower portion of the conveyor belt 311 is supported by rollers 455 which are rotatably mounted. at each end in upwardly projecting brackets 458 which are mounted on each side of the channel bar 433, by any suitable means such as screws 451.

Now, as is often the case, the flaps 353 and 354 of the blank B, as they are fed into the machine, are not of the same length and in most cases this difference in the length of the flaps 353 and 354 will, of course, change the position of the meeting place of the proximate ends of the flaps 353 and 354. Ordinarily, by adjusting the plates Ill and H8 on a horizontal plane relatively to each other, the proximate ends of the flaps 353 and 354 may be caused to move through the machine at approximately the position shown in Figure 8. However, there are many instances where one of the flaps 353 or 354 may be very short or very close to one or the other of the two sets of rollers 230, as observed in Figure 8, and the other flap will be very long so that the meeting place of the two flaps or the proximate ends thereof will be very close to one of the sets of rollers 208 and it will be impossible to adjust the conventional plates H1 and H8 so that the proximate ends of the flaps 353 and 354 would be in the path of the tape applying means. Due to this proximity of the proximate ends of the flaps 353 and 354 to the rollers 28!) the dovetailed bar I80 is provided and the frame I85 of the tape dispensing mechanism has sliding movement thereon guided by the dovetailed members 285 and 253. Before the tape mechanism frame I85 may be adjusted, however, the set screw III! in the block I83 (Figure 8) must be turned so that the shipper shaft 93 may have horizontal sliding movement in the block I83. The screw 3, in Figure 1, must also be loosened so that the bar 322 and associated parts may also be moved crosswise of the machine inasmuch as the bar 322 is integral with the tape mechanism frame I05. The shafts 334 and I28 will have horizontal sliding movement in the sleeves 345 and I22, respectively, by turning the hand wheel 233 the shaft 288 will be rotated and since the shaft 288 is threadably mounted in the outwardly projecting portion 281 of the tape mechanism frame I35, the rotation of the shaft 288 will cause the tape mechanism frame I85 and associated parts to be moved in the desired direction crosswise of the machine. The shafts I28 and 334 will have relative sliding movement in the sleeves I22 and 345, respectively, and, in the event that the sleeves I22 and 325 are not long enough, other sleeves which are longer may replace the sleeves I22 and 345.

The frame member I and the longitudinally disposed bar 322 having been moved to the desired position, the set screw IIJ'I in the block I33 is then tightened down against the shaft 83 and the screw 34! is tightened in the bar 322 through the slot 342, and the machine may then be operated in the conventional manner.

However, the conveyor 315 must also be adjusted so that the center of the same is in alinement with the center of the tape I'BI]. In this instance, it is necessary to loosen the set screws 385 and 388 in the pulleys 318 and 382, respectively, then loosen the nuts 423 that secure the hooks M1 to the horizontally disposed channel members M8 .and it is then necessary for the operator to slide the bearing blocks 398 along the shaft I2 to the desired location as well as the bearing blocks 39I along the shaft II to the desired location. Simultaneously the hook members 4!! must be moved along the slots 425 in the horizontally disposed channel members MB of the inverted U-shaped frame members 428 and 42I. The set screws 385 .and 386 are then tightened against the shafts I2 and II, respectively, and the nuts 423 are tightened against the channel bar H8 and then the machine is ready for operation.

In the drawings and specification there has been set forth a. preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only, and not for purposes of limitation, the scope of the invention being defined in the claims.
